preemptive scheduling

 We have been assuming in chapter 3 that preemption incurs no over head. Let us now relax this assumption. Consider a 2 task system. Preemption overhead is x. Given e1 , e2 , P1 , P2 , obtain the maximum value of x for which the two tasks are RM schedulable. Note: e1, e2 are execution times. P1, P2 are periods.
